Specification of Letters Patent.

Patented Feb. 18, 1913.

Application led January 14, 1911. Serial No. 602,587.

To all whom t may concern Be it known that I, OLMEDO CORTEZ WY` SONG, a citizen of the United States, residing at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Morl tising-Machines, of which the following is a specilication.

My invention relates tO improvements in l shaft C. The boxes are adapted to be raised One Of its objects is to pro-vide a machine mortising machines.

adapted to produce curved mortises, and

adapted to mortise chair backs, chair seats.`

and similar` articles.

whereby the arc ofthe curved mortises may be varied.

Another object is to provide improved work supporting, holding and feeding mechanism, and which is adapted to hold work of varying shape and character.

It further consists in certain details of form, combination and arrangement, all of which will be more fully set .forth in the description of the accompanying drawings, in which:

Figure 1 is a front elevation of my improved mechanism. Fig. 2 is a side elevation of the same with a portion Of the frame broken away. Fig. 3 is a vert-ical section through the work table on line t t of Fig. 5, with the parts arranged to hold chair backs.

Fig. 4 is a similar viewl showing the parts arranged to hold chair seats. Fig. 5 is a top plan view of the work table as shown in Fig. 4. Fig. 6 is a front elevation of the tool spindles and their supports detached. Fig. 7 is a detail view similar to Fig. 6 illustrating a modification. Fig. 8 is a perspective view of one of the tool spindles and its supports detached. Fig. 9 is a detail side elevation of the same partly in section. Fig. 10 is a detail sectional view on line m of Fig. 8. Fig. 11 is a detail sectional view on line 'u o of Fig. 8. Fig. 12 isa det-ail perspective view of the work supporting forms. Fig. 13 is a perspective view of a mortised chair seat. Fig. 14 is a perspective view of a mortised chair back. Fig. 15 is a front elevation of the tool spindle carrying mechanism detached, and illustrating a modification thereof. Fig. 1G is a side elevation of the mechanism illustrated in Fig. 15. Fig.

17 is a sectional detail of part of the spindle spacing mechanism. Fig. 18 is a sectional .detail similar to Fig.'4 illustrating a modifcatio-n thereof.

In the accompanying drawings A represents the frame of the machine. The upper portion of the framev is provided with vertical ways a a on which slide lboxes B which in turn support Opposite ends of a rod or and lowered in unison by means of screw threaded shafts attached at one end to said boxes. The upper ends of said shafts are respectively threaded through hand wheels Another object is to provide mechanism` b the hubs of which are provided with sprocket wheels b2 and rest-upon cap plates attached to the top of ways a a. The sprocket wheels 52 are united by a sprocket chain 293 to cause them to move in unison in raising and lowering the boxes B.

I have illustrated two modifications of tool spindle carrying mechanism. As illustrated in Figs. 1, 2, and 6 central extensible arms C C2 dep-end from the shaft C and are composed of upper sections c which telescope into sections o', and are adapted to be adjusted by bolts 02 passing through ears c3 on the sections c and threaded through ears on straps or'collars 04 adjustably clamped to sections c to lengthen or shorten said arms. Bolts 05 passing through slots in sections o and tapping sections c serve to -clamp the sections to adjusted position. Sections c at their lower ends are provided with journal boxes c6 o" in which are journaled opposite ends of a mortising yspindle vD, armed at its forward end with a mortising tool d. A belt pulley 0l on the spindle D serves to drive said spindle. At opposite sides of said central arms are similar adjustable arms C3 C4 which are also supported by the shaft C and at their lower ends are provided with journal boxes o8 o9 in which are journaled the ends of mortising spindles D D2 adapted to be respectively driven by belt pulleys d2 d3, and provided with mortising tools d. The arms C3 C4L are also respectively provided with journal supports 01 c forthe shafts of idler pulleys 012 cl3. If desired a greater or less number of mortisin spindles may be supported from the shaft The arms supporting the spindles D D D2 are provided with slotted links d6 ai7 piv- Y the adjustment of the links Z6 57.

As illustrated in Figs. 1 and 2 the spindles D D D2 are reciprocated in unison with the axis of shaft C as a center, by means of a .pitman E pivotally connected at one end to the lower end 015 of one of the arms C and Vat the opposite end to an adjustable crank pin attached to a T-slot e in the face of a crank wheel e carried by a shaft e2 adapted to be driven by a belt on the belt pulley e3. The spindles D D D2 are preferably driven by means of a single belt F receiving motion from above the machine by means of a suitable countershaft and engaging respectively the pulleys cl2, 012, d, 013, cl3. By raising and lowering the shaftC and adjusting the length of the arms C C2 C3 C4E the degree of curvature of the mortises may be varied as re uired. 4

s illustrated in Figs. 15, 16, and 17 the tool spindles are represented by 2, 3, and 4, and are journaled to sliding members 5, 6,

and 7 which are mounted in ways Son the members 9, 10, 11. The member 10 is supported from shaft 12 by an eye 13 at its upper end and also by an eye 14 at the end of bracket 15 forming part of member 10, and is adapted'to be locked to the shaft 12 by set screw 16. The members 9 and 11 are pivotally supported upon the shaft 12 respectively by eyes 17, 18. Screw rods 19 vpivotally connected to the respective members 9, 10, l1 and threaded to the members `5, 6, and 7 serve to adjust the members 5, 6,

and 7 upon their ways 8 on members 9, 10, and -11 to vary the distance between the tool spindles and the shaft 12. I preferably connect the several screw rods 19 by gears 20, 21, 22 so that said several screw -rods will move in unison to adjust the several tool spindles. A gage 23 and pointer 24 enable the operator to adjust the spindles to any desired position. In order to, vary the distance between the respective spindles I provide two right hand threaded rods 25 pivotally attached'to' member 6 and two sleeves 26 having threaded engagement interiorly with the rods 25, and eXteriorly Ythreaded with left hand threads which eni Vgage nuts 27 which are pivotally attached by centers 28 respectively to-members 5 and 7. The sleeves 26` are providedrwith hand .wheels 29 which when turned adjust the sleevesrelative to the nuts 27 and also the nrods 25 within Vthe sleeves-securing a double I screw feed and quick adjustment of the disson of the telescoping of the rods 25 and sleeves 26 a compact mechanism adapted to the limited space available. v

As illustrated in the modification Fig. 7, the shaft e2 is provided with a crank viheel e4 and an adjustable eccentric e5, and the pitman E driven by the crank wheel serves to reciprocate the spindle D, while the bearings of the spindles D D2 are connected together by a link e6 and reciprocated in unison by means of a pit-man eT operated by the eccentric e5, the links ai and d? being omitted. This arrangement permits mortises of different length to be produced by the respective mortising tools.

G represents a work supporting table which is mounted upon horizontal guides or ways g carried by a vertically adjustable frame H. The frame H engages vertical ways on the frame A at /L and is vertically adjustable by means of a hand driven shaft 7L which by means of beveled gears h2 h3 drives the screws b4 which are threaded into the cross bar 11.5 of frame I-I and serve to raise and lower said frame to bring the work into alinement vertically with the mortising tools. The work table is reciprocated horizontally to and from the mortising tools upon the ways g by means of a rock shaft g actuated by hand lever g2, said rock shaft being provided with crank arms g3, the free ends of which engage notches g4 formed in opposite ends of the table G.

Chair backs S or other work of the general character indicated by Fig. 14C are held upon the work table during the mortising operation in the following manner: I represent vertical standards carried by the table G, which standards are united at the upper end b a cross plate J. A metal plate K is clalnpe to plate J by slotted arms 7c so as to be vertically adjustable relative to plate J. To the lower face of plate K is secured a convex form or block 7c preferably of wood, of the radius desired.' A counterpart or concave form or block L preferably of wood, of the desired radius is mounted vupon a metal support M, the lower potrion 1n of which seats in a recess m in the table G, so as to be vertically movable, but supported against horizontal movement relative to the table, and free to be lifted from the table. A rock shaft N journaled to the table G is actuated by hand lever N and provided with an eccentric n upon which rides a follower a supported against lateral movement by and adapted to move vertically within the recessm, and to engage and raise and lower the support M, thus enabling the work S to be rmly clamped between the forms 7c L. By providing the adjustable parts K M adapted to receive wooden forms, the respective operators are enabled to readily provide forms of the exact curvature or outline required for their particular class of Work, also the Wooden forms serve to `firmly y clamp the Work and even to restore Warped' attached to the plate J, adjustable guidesk or stops p p are adjusted relative to plate J to support the upper portion of the Work, While the lovver edge or portion of the Work is supported by the form P. .A rock shalt R operated by hand lever 1 and provided with an eccentric 1" serves by the engagement of said eccentric With the Work to lock the Work in place.

In Fig. 18 is illustrated a modification of the mechanism illustrated in Fig. 4:, in which the seat T is held at an angle supported by the block P and stops p. The eccentric shaft R is ournaled in adjustable bearing members 1-2 guided by slotted brackets J projecting from plate J. The eccentric 7" also carries shoes 'r3 to bear upon the seat T. The rotary mortising tools are seated in counter-bores in the end of the respective tool spindles, the ends of the tool spindles being split and adapted to be clamped upon the shank of the tools by means of nuts Z9 engaging tapered threads on the end of the spindles as indicated in Fig. /9.

The mechanism herein illustrated and described is capable of considerable modification Without departing from the principle of my invention.
